Error - Reseller: The max. number of APS instances for your account is reached.

hi, i searched the forum and used google, but i can't find any clue to resolve the error.

I use ISPConfig on my servers, as Admin i can install as many APS as i want, but not in my reseller/client account. In the Limits of the Client-account i have set "Max. number of APS instances" to -1 or to 100, 1000 but still got the Error:

Error
